According to the Center for Disease Control and Prevention (CDC), up to 20% of Americans contract the influenza virus each year, and approximately 3% of all births in the United States result in birth defects each year. Consider two babies being born independently of one another. The probability that neither baby contracts the influenza virus in a given year is

The probability that neither baby contracts the influenza virus in a given year is 0.640.

Step-by-step explanation:

Probability of catching influenza virus = 20% = 0.2

We can find the probability of not catching the influenza virus as:

Probability of not catching the influenza virus = 1 - (Probability of catching the influenza virus)

                                                                             = 1 - 0.2

Probability of not catching the influenza virus = 0.8

If two babies are born independently, we can compute the probability that neither of them catches the influenza virus as:

0.8 x 0.8 = 0.64

The probability that neither baby contracts the influenza virus in a given year is 0.64.

3 is greater then both of those numbers

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
